Which data structure is used to implement recursion?
Step 1: Understand what recursion is. Recursion is when a function calls itself to solve a problem.
Step 2: Know that when a function calls itself, it needs to remember where it left off. This is where a data structure comes in.
Step 3: Learn that a stack is a type of data structure that works like a stack of plates. You can only add or remove the top plate.
Step 4: When a function calls itself, the current function's information (like where it is in the code and its local variables) is pushed onto the stack.
Step 5: When the function finishes, it pops off the top of the stack to return to the previous function call.
Step 6: This process continues until all function calls are completed.
